Abstract

A quantitative assessment of toughness transfer (I), for a composite with a rate sensitive matrix-resin, can be achieved when the crack opening displacement rate (COD) in the double cantilever beam (DCB) and single edge-notched bend (SENB) specimens is reconciled. A method to reconcile I COD in standard composite DCB and resin SENB tests is presented, where the focus is on fracture initiation. The method may be useful when assessing matrix-to-composite toughness transfer at crack initiation, especially for composite systems in which the matrix toughness is rate sensitive.
